Is ETICS responsible for mold formation?

Calculations back and forth, you can’t rely on them 100%. I am rather more skeptical. I have already seen insulated facades practically drowning, especially during the thaw period. This can lead to mold growth. In my opinion, this is only about convincing people that a [WDVS] can save a lot of heating costs. I often find that exaggerated and it’s pure advertising. In practice, it often looks different.
